After years of being absent from her hometown, the unusual death of a young girl brought Zoey Foster - a shapeshifter with secrets to hide - racing home. Returning to her hometown is tough, made even worse when Zoey's estranged family isn't so eager to see her. The mother who is bitter that Zoey didn't follow in her footsteps and become a Tracker for the Supernatural Council. The twin sister who looks at her with disgust. At least her younger sister and father seems more welcoming. But unknown to her family, Zoey is on the trail of dangerous creatures. She is seeking the truth, but the truth may lead her to her very own demons - creatures she thought she had rid herself off years ago - when she died and was brought back to life. Only, when she was brought back to life all those years ago, she wasn't herself anymore. Something dark. Empty. Something stronger. Faster. A supernatural creature the world has never seen before.
